  IOSmart  
 

IOSmart allows for the flexible configuration of logical drives, logical volumes and logical partitions and ensures instant RAID availability via background logical drive initialization. Fibre loops' load balancing is provided within the subsystem. The firmware' s Adaptive Write Policy and Guaranteed Latency I/O algorithms improve write
performance and ensure fast and continuous data flow.

 
  DrvSmart  
 

The DrvSmart utilities manage disk drive defects and help ensure data integrity. One of the main DrvSmart
functions, Media Scan, retrieves data from degraded or damaged hard drives and handles low quality drives in both the degraded mode and during the rebuild process. Other DrvSmart features include disk cloning, drive roaming, SMART, transparent resetting of non-responsive hard drives, RAID parity update tracking and recovery.

 
  SysSmart  
 

SysSmart combines enclosure monitoring and firmware management capabilities in order to minimize the chance of down time caused by hardware failures. The SysSmart functions include the event-triggered cache flush and the various monitoring approaches combined with the powerful RAIDWatch manager. Component status, voltage and temperature readings, and system events are instantly revealed through the manager's graphical interface.
